Abstract

Water contamination has negative effects on people's quality of life and the environment in recent decades as a result of increased agricultural and industrial activities. Using new advanced nanomaterials can be helpful for the removal of water contamination. In this study, novel hydroxyapatite/zinc Oxide nanocomposites was prepared via a simple ci-precipitation route. Hydroxyapatite has been known as a biocompatible nanomaterial. Prepared samples were analyzed via X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and Fourier-transform infrared spectroscopy (FTIR) analysis. It was found that hydroxyapatite/zinc Oxide nanocomposites can be provided as an attractive candidate for photocatalytic degradation of azo dyes. The prepared Hydroxyapatite/Zinc Oxide nanocomposites were utilized as a photocatalyst for degradation of methylene blue and acid blue 92. Results showed that prepared hydroxyapatite/zinc Oxide nanocomposites can be degraded 87% and 98% of rhodamine B and methylene blue under UV irradiation respectively. It was observed that hydroxyapatite improve the photocatalytic activity of zinc oxide.
